android-notifications

In iOS we have a feature to update the app icon with the new pending messages for the user by showing a small number on the right-top corner of the icon and similarly I would like to know if we have method to update a ImageView/ImageButton in android(Here I am not looking to update the icon on the home screen but inside my app). For example, the pic shows the red background icon with the number of messages pending to be read in red and if there are no messages it shows with a gray background. Thanks, I was interested in this SO as I didnt know how to do it neither. So I started looking into it

I have a small problem but dont understand how to get out of this. I created a class for providing Notifications, but these lines are marked deprecated: ... Notification notification = new Notification(icon, text, time); // deprecated in API level 11 ... notification.setLatestEventInfo(this, title, text, contentIntent); // deprecated in API level 11 ... Alternative methods are: ... Notification noti = new Notification.Builder(mContext) .setContentTitle("New mail from " + sender.toString()) .setContentText(subject) .setSmallIcon(R.drawable.new_mail) .setLargeIcon(aBitmap) .build(); // available

I am trying to implement NotificationListnerService which is added in android 4.3 but I am not able to get the notification details. My code are as below public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this); mBuilder.setSmallIcon(R.drawable.ic_launcher); mBuilder.setContentTitle("notification test"); mBuilder.setContentText("Notification text"); mBuilder.setAutoCancel(true); Intent

I know that C2DM registrations expire, and you are supposed to periodically refresh the registration ID. Is this the case with GCM? by looking at the following code on the Android GCM guide (shown below), it seems like you only do it once and don't need to refresh, but I dont see that explicitly written anywhere, so I just wanted to check. final String regId = GCMRegistrar.getRegistrationId(this); if (regId.equals("")) { GCMRegistrar.register(this, SENDER_ID); } else { Log.v(TAG, "Already registered"); } EDIT: THIS ANSWER IS WAY OUT OF DATE, I HAVE NO IDEA WHAT THE CURRENT BEHAVIOR IS I found
